I want to get a 20 ga 870 express and shoot the new hevi-shot (probably Winchester in4 or 6 shot and had thought about Nitro Co. ammo). I contacted Nitro and they said to get a Rhino choke with .575 constriction, I checked and found that that choke is $95. I don't want to invest that much in a choke, does anyone have a less expensive choke recommendation that will shoot (hopefully) what I want to?
